Welcome on board. I’ve two tips:
1) Don’t post so many at once. People will be less inclined to comment on so many shots. Keep it to your best one or two photos.
2) Read the guidelines on posting. I don’t follow links to other sites to look at photos and I reckon there are others who are the same as me. If you can’t be bothered embedding the photo in the post then why should I bother looking at it?
If you edit the post I’m sure you’ll get a better response.
Peter, 2 and 3 stand out from the others. I notice that you shot in ‘landscape’ mode for number 3, which is supposed to set a reasonably small aperture to keep a good depth of field. However you will note that the aperture set was f5.6 which is not small enough for what was required! Try putting it in aperture priority mode and using f11 or f16.
Number 4 is the weakest by a long shot (pardon the pun). The foreground is underexposed and there is no real subject to keep any interest. If necessary you need to merge 2 shots, one for the foreground and one for the sky, or else use a ND grad filter to balance the exposures between the sky and the foreground.
